Subject [jira] Updated: (DIRSERVER-803) Creating an alias from a child entry to the ancestor causes an error (return code 36)
Date Sun, 26 Aug 2007 23:45:30 GMT

     [ https://issues.apache.org/jira/browse/DIRSERVER-803?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alex Karasulu updated DIRSERVER-803:
------------------------------------

          Component/s: core
    Affects Version/s:     (was: 1.5.2)
                       1.5.1
                       1.0.2
                       1.0.1
                       1.5.0
                       1.0

Yep you guys are right the server's alias handling code presumes cycles do 
not exist from descendant entries to any one of their ancestors.  The algorithm
could be modified to handle these cycles but that's not a quick endeavor so 
I will put it off as E suggested.

> It fails to import the following two entries into ApacheDS 1.0 (default server.xml).

> The second entry is an alias to the first one, and is directly located below the first
entry:
> dn: ou=Singers,dc=example,dc=com
> ou: Singers
> objectclass: top
> objectclass: organizationalUnit
> dn: ou=Songwriters,ou=Singers,dc=example,dc=com
> ou: Songwriters
> objectclass: top
> objectclass: organizationalUnit
> objectclass: alias
> aliasedobjectname: ou=Singers,dc=example,dc=com
> Here is the result I got from an ldapmodify attempt:
> $ ldapmodify -h localhost -p 10389 -D "uid=admin,ou=system" -w ****** -q -c -a -f aliasSingers.ldif
> ldap_add: Unknown error
> ldap_add: additional info: failed to add entry ou=Songwriters,ou=Singers,dc=example,dc=com:
[36] aliasDereferencingProblem - attempt to create alias with cycle to relative ou=Singers,dc=example,dc=com
not allowed from descendent alias 2.5.4.11=songwriters,2.5.4.11=singers,0.9.2342.19200300.100.1.25=example,0.9.2342.19200300.100.1.25=com
> It seems that ApacheDS does not allow to create an alias from a descendant. I tried the
same with Tivoli Directory Server 6.0 and Sun Java System Directory Server 5.2, both allowed
this constellation.
> Find attached a JNDI JUnit test which is able to cause the error by adding two entries
programmatically.
